Historic Philadelphia School Saved by Recycled Content

Friday, January 29th, 2016

In the Fall of 2015, the Horace Furness High School received an Acrymax HP-1 Fully Reinforced Coating System that preserved its existing standing seam and flat seam metal roofs. This is a fluid applied coating system that provides a 45 mil fully reinforced elastomeric membrane system. The primary components in this system were Acrymax’s Elastomeric Coatings w/ Recycled Content.

Upon completion, the Horace Furness High school received a water tight roof that will be easy to maintain in the future. We were able to assist in saving this historic roof while providing the school district with tremendous cost savings over alternatives all while using recycled content products to do it – What is more sustainable than that!!

The coating work was completed by Sioutis Coating Enterprise as a sub-contractor for Ganter Contractors, Inc. The specification was written by Vitetta with consultation work from Steve McLaughlin Roofing Consultant

Horace Howard Furness High School is a secondary school part of the School District of Philadelphia. It is located in South Philadelphia at 1900 S. Third St., Philadelphia, Pennsylvania. It was originally built in 1914 and was added to the National Register of Historic Places as Horace Furness Junior High School in 1986.

Elastomeric Coatings: Can they be too thick?

Tuesday, November 26th, 2013

Most elastomeric coatings function better when they are thicker. Each additional coat adds mil thickness and unlike other coatings especially asphaltic products which become brittle when they are thick, the added dry film thickness (DFT) enhances properties of elongation and tensile strength.

Imagine a very thick rubber band versus a thin rubber band. Which one do you think will last longer?

If our only concern was tensile strength and elongation,  then we should lay down as thick a coating system as our budget would allow. However, elastomeric coatings also bring other properties to the table.

In wall coatings, permeability or breathability is an important property not to forget.

Elastomeric wall coatings like Acrymax AF135 are designed to breath. So while keeping the building waterproof to rain and other moisture,  elastomeric coatings allow for the natural breathing of masonry surfaces without affecting the adhesion of the coating.

However each additional coat applied to the surface reduces the breathability of the coating system. Eventually the water vapor that used to move freely out of the masonry will now gather behind the coating and condense into liquid water. This water will lead to delamination of the coating (no matter how well the base layer is adhered) and the formation of a blister. Eventually this blister will rupture and cause a major coating defect.

So while this is not the norm with elastomeric coatings (they are typically applied too thin), this phenomenon is still something that needs to be kept in mind when working with and specifying elastomeric wall coatings.

Keep in mind, with roof coatings you generally want a less breathable surface and too much thickness is much less concerning.

LEED Recommended For All General Services Administration Buildings

Wednesday, May 29th, 2013

Early this month, the Green Building Advisory Committee, officially recommended that all General Services Administration (GSA) buildings use the LEED green building certification system. The Green Building Advisory Committee was established by GSA in 2011. The reason for this recommendation is to measure the buildings efficiency. The committee also communicated that LEED should be the primary way to show how agency buildings use energy and water and that LEED standards are the best way to help meet the Energy Independence and Security Act.

Roger Platt, senior vice president of Global Policy & Law, USGBC said, “GSA has been a leader in energy and sustainability, and we are thrilled to see the leaders in the public and private sectors continue to recommend LEED as the best choice for GSA to maintain its leadership status while improving sustainability, reducing energy and saving money for its buildings.”

The Pacific Northwest National Laboratory (PNNL) recently did a study that found LEED certified building use 25 percent less energy than the national average and cost 19 percent less to operate. Click here to learn more about LEED.

Acrymax is a member of the U.S Green Building Council (USGBC). We offer products that help achieve LEED points. Products include solar reflective coatings and coatings that contain recycled content. Acrymax will be exhibiting at the Greenbuild Expo in Philadelphia November 20-22.

Elastomeric Coatings on Commercial Structures

Wednesday, May 15th, 2013

The Dow Chemical Company which is a supplier of Acrymax wrote a recent article in Durability and Design. The article is titled Elastomeric Acrylic Coatings for use on Commercial Structures. The article discusses why you should use elastomeric coatings for roof coatings, exterior insulation and finishing systems, and exterior wall coatings for concrete and masonry surfaces on commercial architecture.

Elastomeric coatings have unique properties that make them a great choice where elongation and flexibility are needed.

The article breaks down elastomeric acrylic coatings uses in three ways:

  • Elastomeric roof coatings
  • Exterior insulation and finishing systems (EIFS)
  • Elastomeric acrylic wall coatings

Elastomeric Roof Coatings
There are two important reasons for acrylic roof coating. First, it protects the roof from all the elements of weather. Second, with a finish color of white a “cool roof” is created which helps fight the urban heat island effect. A cool roof  keeps the building from having excessive heat buildup and makes the roof energy efficient. Some elastomeric coatings become dirty and they lose their reflectivity as they age. So you should select an elastomeric roof coating that will be dirt-resistance. Acrymax would be a great choice in this avenue!

Exterior Insulation and Finishing Systems
Elastomeric acrylic polymers are sometimes used in EIFS finish coats more specifically flexible-textured finish coats. The benefit to using flexible-textured coats is that the polymer is very soft which offers better crack-bridging properties. The crack-bridging properties and good elongation of elastomeric acrylics help to maintain the continuous membrane even with movement.

Elastomeric Acrylic Wall Coatings
Concrete and masonry surfaces are very susceptible to surface cracking, but using elastomeric acrylic wall coatings can help this. Elastomeric acrylic wall coatings possess a hydrophobic nature and can be applied in thick films which offer good barrier properties. These coatings can be used to bridge hairline cracks, but you must use a thick enough film.

Elastomeric acrylic coatings have many benefits and properties that make them a great choice for these applications on commercial structures. Click here read the full article and see the tests they performed.

What is the Best Application Equipment?

Wednesday, April 17th, 2013

So now you have the product with which you plan to coat your roof. How should I apply those coatings and what equipment will I need?

In this blog, we will talk about the different equipment you can use, and where they are most applicable.

Brief summary:

  • Brushing is suitable for small areas, edges or corners.
  • Rollers are useful on larger and relatively flat surfaces.
  • Spraying is best for large areas, but also works very well on irregular shapes.

Brushing is slower than other methods of paint or coating application. So you would mainly use brushes for small areas and cutting in corners or edges. Generally you want to use a good synthetic bristle brush.

Rollers are great for use of large and flat areas. They don’t require as much skill as spraying. Rollers are not as effective in applying paint evenly. You have to be careful with application using a roller you can produce unintentional roller marker or a “stipple” effect. Generally for latex paints such as Acrymax you should use synthetic fiber covers.

Airless spray is great for covering large areas but requires more skill to use. When you use airless spray you need to first choose the tip you will be using. For more information on what is required in choosing the spray tip click here. While spraying you typically want to hold the sprayer so the tip is 10-12 inches from the surface. The secret to good spray painting is to apply even coats.

You may need to use more than one method to complete your job. Make sure you use the correct equipment for the best results.

Attention: Building Owners – Schedule your roof inspection today!

Wednesday, April 3rd, 2013

As the saying goes, April showers bring May flowers. Unfortunately they may bring roof leaks as well.

Winter is tough on your roof. The damage the harsh weather can cause and the roof leaks that result can cause serious harm to your building. Your roof should be inspected at least 2 times per year (or more) and it is wise to schedule inspections in the Spring and the Fall. You should also inspect your roof after the occurrence of significant weather events that may have damaged your roof.

Visual inspections of your roof should include:

  • Inspection of roof membrane, flashings, roof drains, gutters, and other components of the roofing system for any damage that may have occurred.
  • Identification of conditions that may affect the long-term performance of the roof.
  • Development of list of corrective actions needed.

Most damage can be easily repaired with Acrymax coatings. Applying Acrymax coatings in combination with fabric reinforcement can seal cracks, repair flashings, and fix other roof problems.

  • Acrymax elastomeric coatings including AF-130BC and AF-130 are available in 1 gallon or 5 gallon pails.
  • AF-315 is a unique heavy bodied fibrated material that is especially useful for roof repairs. AF-315 is also available in 1 and 5 gallon pails.
  • Poly-1 reinforcement fabric is available in 4”, 6”, 12”, 18”, and 40” widths and varying lengths.
  • Another great product for roof repair is Eternabond. We offer this self stick tape with reinforcement in 4”, 6”, or 12” widths.

Roof inspections are a critical first step in keeping your roof in shape. So check out your roof today! If you would like us to recommend an Acrymax approved applicator to inspect your roof give us a call at 800-553-0523.

Spring is Here: Coating System Installation

Wednesday, March 20th, 2013

Part 3 of 3

With the first day of spring, we want to focus on coating system installation and specifically on weather!

Spring is a great time to apply coatings, but like anytime of the year, applicators should be conscientious of the weather. Waterborne coatings require good exterior painting conditions. At a minimum, you will want 24 hours of 45 F temperatures and no rain/dew in the forecast.

A Few Do’s & Don’ts

  • Avoid freezing temperatures
  • Don’t take chances with rain or dew
  • Be observant of the weather conditions as they can quickly change
  • In very warm or cold temperatures, apply coatings in multiple thinner applications rather than 1 or 2 heavy applications.

Remember that spring is one of the heaviest seasons for pollen! This may deposit on your roof and needs to be cleaned off between coats

For a complete recommendation on weather conditions, please see ATB-101.

Please explore the previous segments in our lead up to spring, roof systems selection & preparation.

Spring is on the Way: Prepare for Coating

Monday, March 4th, 2013

We’re getting closer; only 17 days now until spring! In our last blog we talked about Roof System Selection. This week we want to focus on preparation. Preparation is one of the most important and critical steps for successful and long lasting roof coating applications.

You must make sure the preparation of the roof is done correctly to get the best results for a long lasting roof. First step in the preparation is removing all the dirt, debris, oils, and contaminants from the roof. This can be done by the following methods:

  • High Pressure washing
  • Vacuuming/Air-blowing
  • Mechanical cleaning

Beyond your standard contaminants (dirt, debris, etc.), your project may have contaminants that require more rigorous methods to remove.  Corrosion needs to be well prepared and may require wire brushing or other aggressive methods. Biological growth may require chemical cleaning additives. Certain surfaces like EPDM are generally wash-primed with products like Acrymax PR-101 in order to accept coatings.

Preparation is a crucial step in any coating system process and should be evaluated. This can be done with a tape test which involves applying masking tape to the surface, and then peeling off the tape. If there are contaminates on the tape that will interfere with adhesion of the coating, further cleaning or use of a primer are necessary. A primer is NOT a substitute for good preparation.

Acrymax Technical Bulletin ATB-103 describes preparation methods and how to evaluate the effectiveness of the preparation method used.

Spring is on the Way: Roof System Selection

Tuesday, February 26th, 2013

Only 21 days till the first day of spring! Make your roof even better with preventive maintenance! Or give that neglected roof some TLC!

No matter your existing roof type, Acrymax has a coating system that will fit your needs. Selection of the base layer/primer to any coating system is crucial.

  • An existing asphalt roof should be initially sealed with AF-127 to lock up its chalky nature.
  • A metal substrate may be primed with our PC-125 or PC-535 for corrosion protection
  • Masonry surfaces generally are primed with AF-100 or AF-110 due to their porosity.
  • Single-ply roof like EDPM will be cleaned with PR-101 to promote adhesion, while TPO roofs have a specially designed elastomeric basecoat, AF-130TPO, for the same purpose.

After determining your substrate, the next step is to select the correct roofing system for your roofs condition. Acrymax offers three main systems from which to choose:

  • ARS-3 Protective Coating Systems
    The ARS-3 is protective coating system that will stabilize your current roofs condition. It can provide reflectivity and architectural color, but is designed for roofs that are good to excellent condition (i.e. no leaks).
  • ARS-2 Partially Reinforced Roof Systems
    The ARS-2 partially reinforced protective coating system stops roof leaks by targeting critical areas (seams, flashing details, transitions) on the roof with fabric reinforcement. The hybrid nature of this system allows for ARS-2 systems to be engineered for the needs of specific project. Typically used for roofs in fair to good condition.
  • ARS-1 Fully Reinforced Roof Membrane Systems 
    ARS-1 is Acrymax’s most comprehensive approach to a roof coating system, providing complete reinforcement to the entire roof surface. This system wills “put-to-bed” issues for years to come. Generally used as a recovery system for roofs in poor to fair condition, but this system also has applications in new construction as well.

Check out the Roofing Systems to find more information on the systems to use for your particular type of roof.

Acrymax Joins Cool Roof Rating Council

Monday, January 28th, 2013

Cool roofing has become a hot topic as of late. Frankly, we find all the current interest to be somewhat amusing since Acrymax has been manufacturing and supplying reflective cool roof coatings since the late 1950’s. You could say that we were ahead of the curve by about 45 years! In any event we are pleased to announce that we have now joined CRRC, The Cool Roof Rating Council, and have submitted our range of reflective roof coatings for testing and listing.

CRRC is a non-profit organization that was created for evaluating and labeling the solar reflectance and thermal emittance of roofing products and to disseminate this information to interested parties such as architects, government agencies, roofing contractors, and others involved in the roofing industry.

CRRC has three goals for radiative energy performance:

  • Implement and communicate
  • Support research
  • Provide education

A main part of CRRC is their Product Rating Program. In this program roofing products that are tested under a strict program administered by the CRRC can be labeled with radiative property values set by CRRC.

Since the 1950’s Acrymax has been formulating, manufacturing, and marketing high performance coating systems. Acrymax provides their customers with the highest quality products and promotes the principals of environmental sustainability with their products and practices. Information about CRRC can be found at http://www.coolroofs.org
